However, this is only supported on the following processors: Intel's K or X suffix processors e. As the name suggests, this option is used to spread the electromagnetic interference EMI coming off the processor across a broader range of frequencies.

This doesn't reduce the total amount of EMI, but it helps prevent all of it from being concentrated on the frequency of interest, namely the processor's clock frequency. This should normally be left on, although if you're doing some serious overclocking, it may help with stability to turn it off.

This is useful if you're overclocking, as higher clock speeds require higher voltages. However, approach this setting gingerly. Even a relatively small change about 15 percent can fry the CPU.

And note that frying doesn't have to show any signs of physical damage to the part. As the name suggests, this is used for adjusting the processor's on-board PCI Express controller frequency. While it might be tempting to tweak this, thinking it could help with graphics, it won't actually do much for the graphics card.

It's best to leave this alone unless you've been touching BLCK, run into stability issues, and have run out of other options to tweak. Both options will adjust the clock frequency of the processor to lower frequencies if it's not doing much and bump it back up to normal if it becomes busy. If you prefer to have your ASRock B85 Pro4 Intel Smart Connect running at full speed all the time, disable this.

The C states denoted by C State are processor power levels. These are useful to turn off when attempting extreme overclocking to keep the processor from switching power states.

If your processor supports it, this will help virtual machines perform at near native level. On older machines, it'll be called "Vanderpool. Sets the operating frequency of the memory. However, unlike BCLK on the processor, you can't chose an arbitrary frequency.

Instead, you're left with options based on the BCLK multiplied by the memory's frequency multiplier. If you're left with strange frequencies after adjusting BCLK, it's best to pick the fastest one that isn't faster than the memory's rated spec.

For best results though, leave this on auto. Big list of timing values Higher-end motherboards will allow you to directly adjust the timing values of RAM; the list of these values is long.

But the most important ones are: If you're overclocking your memory, adjusting those four values will usually help push the overclocking further. The other options you'll find are beyond the scope of this article. This is mostly useful if you're trying to overclock your RAM speed beyond its normal specification.

This value should be handled gently, as going over even a small amount about 15 percent or more can fry the RAM. And frying can happen without apparent physical damage.

The SATA protocol allows for three modes: This is a backward-compatibility feature. It's only necessary if the operating system doesn't support SATA.

Enables all of SATA's features. Desktop Desktop allows you to disable the hot corners when you are working on the desktop.

It also lets you choose whether or not the system boots directly into desktop mode and bypass the Metro user interface. About Displays information about Start8. Not only will it make BIOS setup less diicult but also a lot more amusing.
